Does Orlistat Cause Diarrhoea? Understanding the Facts
Orlistat may cause gastrointestinal side effects including loose stools and diarrhoea, particularly when dietary fat intake is high. This occurs because orlistat blocks approximately one third of dietary fat absorption, and unabsorbed fat passes through the digestive system. Our UK-licensed prescribers assess your individual risk factors during the online consultation and provide personalised guidance on minimising these effects.
Online Prescription Process for Orlistat UK
Our streamlined online prescription service makes accessing orlistat straightforward. Complete your health questionnaire covering medical history and weight management goals. A qualified UK prescriber reviews your information, assessing suitability for orlistat 120mg (from £15.20 with EDM10), Xenical 120mg (from £19.35 with EDM10), or Alli 60mg (from £26.09 with EDM10). Following prescriber approval, your medication is dispensed by our GPhC-registered pharmacy and delivered next-day across the UK.
Managing Gastrointestinal Side Effects
Side effects like diarrhoea can be significantly reduced by keeping dietary fat intake low - approximately 15g fat per meal. Our prescribers provide detailed dietary guidance during your consultation. Very common side effects include oily stools, urgent bowel movements, and flatulence with discharge. These effects are more frequent with high-fat meals and typically reduce as you adapt your diet. Wearing dark underwear or panty liners may help during initial treatment weeks.
Orlistat vs Xenical vs Alli - Which Option Suits You?
Generic orlistat 120mg offers excellent value at £29.69 for 4 weeks (with EDM10), providing identical clinical effects to branded Xenical at £38.69 for 4 weeks. Alli 60mg at £26.09 for 4 weeks provides half the prescription strength, often with milder gastrointestinal side effects. Your prescriber will recommend the most suitable option based on your individual circumstances, weight management goals, and side effect tolerance.
Professional Support Throughout Treatment
Our UK-licensed prescribers don't just issue prescriptions - they provide ongoing guidance for successful treatment. This includes advice on managing side effects like diarrhoea, optimal meal planning to minimise gastrointestinal effects, and monitoring your progress.
